Using a mathematical model of wind currents, supplemented by a module of sediment transfer and sedimentation the spatio-temporal features of the river sediments accumulation on the Don mouth seaside at different wind conditions (eastern and western wind surges and light winds of variable directions) are revealed. It is shown that under the action of the east wind of 6–8 m/s during the entire settlement period (6–7 calendar days) the water movement in the Taganrog Bay is progressive, and under the action of the south-west wind of the same speed, the pattern of current lines changes in time from the progressive movements on the first day to the formation of two circulation zones in the area of the city of Taganrog and in the central part of the Don mouth seaside. It is shown that the fields of suspended matter concentration are similar for different fractions of solids. Under the action of the east wind, they stretched along the extension of the axis of the main branches of the delta at the bay, under the action of the south-west — pressed to the mouths of branches. During the eastern wind surges, the heavy fractions of sediment settle in the area of the Azov–Don navigable canal, and the light ones are carried by the stream towards the bay. During the western wind surges, the sedimentation of the suspended solids occurs near the wellhead, the heavy fractions form three areas of deformation of the bottom near the mouths of the main branches of the delta, the light ones — only two areas.
